' SPECIFICATION forming part of Letters Patent No. 774,318, dated November 8, 1904.

Application filed July l2, 1902. Serial No. A115,312. (No model.)

Be it known that I, GUY M. GEST, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Manhole-Terminals for Conduit-Sections, of which the followingis a specification.

This invention relates to manhole-terminals for conduit-sections; and its object is to provide means for connecting' a terminal section of a conduit for electric conductors with a manhole structure.

In connecting terminal conduit sections with manhole structures it is desirable to provide rounded surfaces at the point of juncture of the section with the walls of the manholechamber to avoid abrupt bends in the conductors contained within the conduit. VIn laying the conduits it sometimes occurs that an end section of a' length regularly maufactured may not be of the exact length required to properly finish a terminalV at the wall of a manhole-chamber, and it is therefore desirable that means be provided to avoid the necessity of cutting terminal sections in order to effect a result such as described.

Iith the before-mentioned objects in View my invention consists of a frame preferably of vitriiied material, adapted to surround the. end of the terminal section and to be slid longitudinally of the latter at or near its point of connection with the manhole chamber, having its end thereof adjacent to the wall of the manhole so formed as to present curved surfaces over which the conductors are adapted to extend.

The invention will be more specifically described in connection with the accompanying drawings, which form part of the specification, and its novel features will be defined in the appended claims.

In the drawings, Figure 1 is a view in perspective of amanhole-terminal connection embodying' the invention. Fig'. 2 is a section of the same on the line 2 2 of Fig. l, and Fig. 3 is a perspective view of a modified embodiment of thel invention. Y

Corresponding parts in all the figures are denoted by the same reference characters.

The reference-numeral l designates a frame Vlar form shown.

adapted to surround and to occupy Various pol sitions longitudinally ofthe conduit-sections, said sections being preferably made of vitrified material and preferably of the rectangu- The end of the section which is adapted' to be secured within the manhole structure has the corners 2, formed by its end face and its inner walls, curved outwardly to present smooth inclined surfaces, and thus avoid the possibility of thereby forming abrupt bends in the conductors where the latter may contact the frames 1.

In the form shown in Figs. l and 2 a single conduit-section 3 is employed with the frame l andV may be solid, as shown in Fig. l, or, as shown in Fig. 3, the frame may be built up of sections, as shown by dotted lines, instead of being molded in a single piece and may inclose one conduit-section, as shown in Fig. l, or a plurality thereof, as shown in Fig. 3;

' The utility of the invention will be readily appreciated, as it affords effective means for connecting terminal conduit-sections to a manhole structure, and by manufacturing the frames in standard sizes with reference to the conduit-sections commonly employedthe labor and time required for connecting the terminal sections may be materially reduced.

While the rectangular form of frame shown in the drawings is entirely practicable and probably the best embodiment of the invention, I would have it understood that I reserve the right to make all such changes in construction as may be included within the purview of the following claims.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. In a conduit for electrical conductors, the combination with a hollow conduit-section, of a hollow frame removably located thereon surrounding and projecting beyond one end of said section its exterior surface being straight from end to end and its interior surface at one end being beveled, substantially as described.

2. Inaconduit for electrical conductors, the combination with a hollow conduit-section, of a hollow rectangular frame removably located thereon surrounding and projecting beyond IOO one end of said section its exterior surface being straight from end to end and its interior surface at one end being beveled, substantially as described.

3. ln a conduit for electrical conductors, the combination with hollow conduit sections grouped together, of a hollow frame surrounding one end of said conduit-sections its exterior surface being straight from end to end and the interior surface at one end being beveled, substantially as described.

4. In a conduit for electrical cond uetors, the
